I'm interested in what you're looking at which says that. Against the dollar 2.5-3 years ago GBP was never below 1.47, since the referendum, the highest it has been is 1.34 and that was the lowest we got in the 2008/2009 crash.
For me that causes a problem as I'm saving for a house in the continent, which I have to pay in EUR, now that I might have to leave the UK as my status is not guaranteed: https://hansard.parliament.uk/commons/2016-10-19/debates/F13...
